Abstract

본 발명은 이동통신기기가 기지국으로부터 착신메세지를 수신했을 경우 착신응답메세지를 송신하기 위한 접속채널을 적응적으로 선택하도록 함으로써 무선교환기가 중첩되어 있는 지역에서 이동통신기기의 수신률을 높이도록 하는 이동통신기기의 호 착신시 접속채널 선택방법에 관한 것으로, 일반적으로 각자 다른 이동통신교환국에 연결된 무선기지국이 중첩된 지역에서는 수신신호세기가 비슷한 채널이 다수개 존재하게 되어, 무선기지국으로부터의 착신메세지에 대하여 이동통신기기가 착신 응답메세지를 전송할 때 착신메세지를 전송한 해당 이동통신 교환국으로 메세지를 전송할 확률이 낮아지게 되며,또한 다른 이동통신 교환국으로 착신응답메세지를 전송하였을 경우 호 접속에도 실패를 하게 되는 문제점이 발생함에 ㄸ라, 본 발명에서는 채널메세지가 송신된 채널번호를 이동통신기기의 기억소자에 저장하도록 하여, 이를 접속채널을 탐색/선택하는 과정에서 이용함으로써 착신메세지를 보내온 이동통신교환국으로 착신응답메세지를 전송할 확률을 높여 수신 성공률을 향상시킨다.According to the present invention, when a mobile communication device receives an incoming message from a base station, the mobile communication device adaptively selects an access channel for transmitting an incoming response message, thereby increasing the reception rate of the mobile communication device in a region where the radio switch is overlapped. The present invention relates to a method for selecting an access channel when a call is received by a device. In general, a plurality of channels having similar signal strengths exist in a region where radio base stations connected to different mobile communication stations overlap each other. When the mobile communication device transmits the incoming response message, the probability of transmitting the message to the corresponding mobile communication exchange station that has received the incoming message becomes low, and when the incoming response message is transmitted to the other mobile communication exchange station, the call connection fails. As this occurs, in the present invention The channel number stored by the channel message is stored in the memory device of the mobile communication device, and the channel number is used in the process of searching / selecting the access channel, thereby increasing the probability of sending an incoming response message to the mobile communication exchange station that has sent the incoming message. Improve.
